Circuit breaker 3-pole 200A BG2 NZMN2-A200 259093

3-pole power circuit breaker 200A is a reliable protection for electrical installations, designed for both construction and industrial applications. The device is characterized by a compact design and flexible mounting, making it a universal solution for a wide range of applications. Equipped with a thermomagnetic release, it effectively protects circuits and cables against overload and short circuit.

Characteristics and application

NZM..-A series circuit breaker, with a rated current of 200A, is designed to protect electrical installations against the effects of overloads and short circuits. Its fixed mounting design ensures stability and safe operation. Short-circuit capacity of 50kA at 400V guarantees effective response in the event of a failure. Optional mounting on a DIN TH rail increases installation flexibility. The device is used in electrical switchboards, control cabinets and other installations requiring reliable protection.

Advantages and benefits

• High breaking capacity: 50kA at 400V ensures effective circuit disconnection in the event of a short circuit, minimizing the risk of damage and fire.
• Flexible mounting: Possibility of mounting both permanently and on a DIN TH rail facilitates integration with various types of installations.
• Wide rated voltage range: Operation in the range of 690…690V allows the circuit breaker to be used in various power systems.
• Thermomagnetic release: Provides protection against overloads and short circuits, protecting cables and devices from damage. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting motors well.
• Solid construction: The device is made of high-quality materials, guaranteeing durability and reliable operation even in harsh operating conditions.
• Compatibility with accessories: A wide range of additional accessories - remote drives, releases, auxiliary contacts - allows the circuit breaker to be adapted to specific application needs.
• Protection included: Supplied with protection, simplifying the installation process and ensuring it is ready to use immediately after mounting.

Design and parameters

The circuit breaker has a lever as an actuator, enabling quick and intuitive switching on and off of the circuit. Protection class IP20 provides protection against contact with fingers and against the ingress of solid objects larger than 12.5 mm. The continuous rated current is 200A, and the short-circuit release setting range is 1200…2000A, allowing precise adjustment to the load characteristics. Power losses are 48W during operation. The location of the main circuit connections on the front side facilitates the connection of wires. The circuit breaker is adapted for screw connection of the main conductors.
